Meet the first corded headset designed for unified communications that's as discrete as it is professionally sounding. The headset's modular over-the-ear design can be worn with two ear buds for stereo, or converted to one ear bud for mono use depending on the user's preference. The ultra-discrete design and superior audio quality you've come to expect from Plantronics make this headset ideal for video conferencing, PC telephony and multi-media applications. With the Blackwire 435, you don't have to compromise between style and sound quality.

Rated 5 out of 5 by mongrel19 Used with Dragon Medical for Mac I use this in the room with the patients while dictating their record. Very accurate mic, and the ability to remove the one earpiece is perfect for our use, as we really don't use the speaker at all. [This review was collected as part of a promotion.] March 12, 2016

Rated 3 out of 5 by Operator The sound is great but I have a hard time keeping the earpiece on, It easily slips off and I have to fuss with it all day. February 16, 2016

Rated 5 out of 5 by Marty65 Need not to look any farther.Dis Da One! I have used several head sets for PS, iPad, Kindel, I bought this one for my Macbook Pro running Dragon Dicatate 4 Mac. All I had to do was plug in and select from System and start the program, flawless.... :) January 16, 2015

Rated 5 out of 5 by AHAagent Comfortable fit for small ears Love the over the ear fitting. So much more comfortable than the over the head sets I had been using. I was using a Microsoft Life-Chat LX-6000 for Business and it has good quality sound but the over head piece is too large for me - it kept slipping around even though it was on the smallest size. Plantronics Blackwire 435M is good quality hearing except for occasional popping, hissing, and lost connection (which may be due to VOIP). People on other end seem to hear me fine unless they have been transferred several times from other agents. Then I call them back and all is good. Also it seems to have a loose connection in the cord if I accidently bump the hand control on the wire. I loose the ability to hear the caller. I like the hand control design for volume control and mute, do not use the connection key. I wish the hand control unit was lower on the wire so that it could lay upon my desk rather than dangling on my chest - I do use the clip. I love the option to use either Stereo or Mono hearing ear pieces. Over all I'm very pleased. August 16, 2014

Rated 1 out of 5 by rewman Constant hissing sound I just received this item and plugged it in only to find it has a constant hissing sound in the background. April 25, 2014

Rated 1 out of 5 by MYates Unable to Ignore Hissing Sound I'm on my second headset since last week. Both had the same problem on multiple computers (tested on both Mac OS and Windows). There is a low-level hiss in both earbuds, and my voice seems to feedback through the microphone into the earbuds. This issue was not present with my previous Plantronics headset, which is a much older model. Tech support was unable to help me with this issue, and the replacement unit had exactly the same issue.Unfortunately, for me this makes it unusable as I need to be able to use the headset for a 6 to 8 hour workday and the noise causes a headache fairly quickly. Not something I can deal with, but your mileage may vary. April 8, 2014
